Pipes, Not Penetrations, Keep Leachate Moving
Fresh Kills to Get Fresher Leachate
Leachate Testing and Evaluation for Freshwater Sediments
Flow Investigation for Landfill Leachate
A two-dimensional unsteady-state moisture flow model has been developed in order to describe the leachate flow process in a landfill. The unsteady variation of leachate mound head has...
Real Time Forecast of Landfill Leachate Flow
A computer model was written to describe the generation of landfill leachate due to large precipitation events. The landfill is described as a multi-layer system, each layer having its...
Exchanging Wastes
For several years, thousands of cubic yards of dried sludge have been stockpiled at the Greater Peoria Sanitary District's wastewater-treatment plant in Peoria, Ill., because...
Leachate Treatment Helps Landfill Expand
Leachate Flow from an Experimental Fly Ash Landfill
Combustion of coal in large-scale utility boilers produces an ash by-product which is often stored in open landfills. An experimental fly ash landfill was constructed by Pennsylvania Power...
Field Investigation for Leachate Flow in a Landfill
Field investigation for leachate flow was done for the Fresh Kills landfill at Staten Island, New York. The leachate monitoring program included data collection from the field for a six...
Characteristics of Colloids in Landfill Leachate
Leachate was collected from a municipal landfill which has been closed for about 15 years. The sample was collected (under a N2 atmosphere) only...
Optimization Study of a Leachate Treatment System
A treatability study was conducted to evaluate the need for a metal precipitation and an ammonia stripping process in a leachate treatment system and to evaluate the biological nitrification...
Behavior of Three Organic Chemicals Passing Through Columns Packed with Sand and Silt in the Presence of Landfill Leachate
This study examines the effect of leachate on the migration of three common industrial chemicals in unsaturated flow under two sets of soil conditions: sand and sand with a layer of silt....
Estimating Landfill Leachate: A Modeling Approach
Use of Lysimeters to Monitor a Sanitary Landfill
A vadose zone monitoring program has been developed using basin lysimeters to evaluate the environmental impacts of a sanitary waste landfill. Lysimeter systems, consisting of collection...
Modeling of Reactive Chemical Transport of Leachates from a Utility Fly-Ash Disposal Site
Fly ash from fossil-fuel power plants is commonly slurried and pumped to disposal sites. The utility industry is interested in finding out whether any hazardous constituents might leach...
Evaluation of the FASTCHEM Model for Predicting Leachate Attenuation at Fossil Power Plants
The Tennessee Valley Authority (TVA) has applied the model FASTCHEM to identify retardation mechanisms and predict solute transport at two fossil power plants. FASTCHEM (acronym for fly...
Visualization Studies of Dense Leachate Plumes in Porous Media
In this paper, a series of flow visualization experiments investigating the behavior of dense leachate plumes are described. These experiments were performed in various flow containers...
Concentration Measurements in Dense Leachate Plumes Using a Gamma Radiation System
An automated, nonintrusive technique is discussed that determines salt concentrations in dense leachate plumes. The dense plumes were introduced from a line source into a relatively narrow...
Burying By the Bale
The Gallatin National Landfill, now under construction in central Illinois, incorporates multiple safeguards to isolate refuse from surrounding water and soil with an inward gradient design....
Landfill Liners from Top to Bottom
Since EPA began requiring geomembrane liners in 1982, liner system components have multiplied rapidly. At the same time, there has been a movement toward relatively large, sophisticated,...
